I have just bought this baby, but I have some weird and serious issues.

Before this card, I had a XFX 9800GT ( green edition, no PCIe power cable used ), it had 2 DVI ports only. Everything worked fine: DVI, DVI->VGA, DVI->HDMI (one piece cable).

After much research, I got to those "invalid format" HDMI issues people have after Windows loads. This is NOT my case. I get invalid format on boot ( only the TV attached to force console output to HDMI )
